I need some confirmation and guidance BEFORE I attempt to restore my iPhone. I am currently Jailbroke (not concerned with unlock, on AT&T) only on my 3GS 3.1.2. I am having some issues and wish to just restore to a fresh 3.1.2 by shift/clicking in iTunes 9.1 and selecting ipsw2,1 3.1.27D11 and then using blackra1n again unless their is a better jailbreak recommendation. I also have ipsw 3.0 and 3.1 and iTunes 8.0, 9.0, and 9.0.3 if I need to downgrade lower. All of my stuff is backed up on Cydia...all the way back to 3.0 I need confirmation and/or guidance if I am doing the right steps BEFORE I do it and accidentally upgrade to 3.1.3 and become another statistic. Would really like to hear from DhLizard or one of the other regulars that provide outstanding replies! Thanks in advance for replies.
